What is the PAPR SR Respirator?

The SR 500 system is a belt-mounted Powered Air-Purifying Respirator (PAPR) with tight fitting facepieces, loose fitting respirators or loose fitting hoods that protects against particulates, gases, and vapors, or a combination. It is designed to be used in oxygen sufficient and non-immediately dangerous to life and health (IDLH) environments. The SR 500 PAPR system functions as an alternative to Air Purifying Respirators (APR) in all situations for which these are recommended. This applies particularly to work that is hard, warm, or of long-duration. The filtered air is supplied through a breathing hose to the tight-fitting facepiece, loose-fitting respirator, or loose-fitting hoods. The above-atmospheric pressure then generated prevents surrounding pollutants from penetrating into the breathing zone. Typical applications include agriculture, asbestos, mold and lead paint abatement, construction & building renovation, demolition, chemical industry, food & beverage processing, lead battery plants, medical & health care, metalwork, pharmaceutical manufacturing, power plants, pulp & paper processing, recycling plants, smelting and foundries, surface preparation, painting, coating, and more.
